PseudoClass images (<TT>class=PseudoClass</TT>) are colormapped RGB images. The colormap is stored as a series of red, green, and blue pixel values. The size of each colormap value depends on the image depth, as shown in the following table: <CENTER> <TABLE WIDTH=80% BORDER=1 CELLPADDING=4 CELLSPACING=3> <COL WIDTH=46*> <COL WIDTH=57*> <COL WIDTH=82*> <COL WIDTH=71*> <THEAD> <TR VALIGN=TOP> <TH WIDTH=18% BGCOLOR="#52799e"> Depth </TH> <TH WIDTH=22% BGCOLOR="#52799e"> Bytes Per Value </TH> <TH WIDTH=32% BGCOLOR="#52799e"> Value Range </TH> <TH WIDTH=28% BGCOLOR="#52799e"> Bytes Per Colormap Entry </TH> </TR> </THEAD> <TBODY> <TR> <TD WIDTH=18% VALIGN=BOTTOM SDVAL="8" SDNUM="1033;"> 8 </TD> <TD WIDTH=22% VALIGN=BOTTOM SDVAL="1" SDNUM="1033;"> 1 </TD> <TD WIDTH=32% VALIGN=TOP> 0..255 </TD> <TD WIDTH=28% VALIGN=BOTTOM SDVAL="3" SDNUM="1033;"> 3 </TD> </TR> <TR> <TD WIDTH=18% VALIGN=BOTTOM SDVAL="16" SDNUM="1033;"> 16 </TD> <TD WIDTH=22% VALIGN=BOTTOM SDVAL="2" SDNUM="1033;"> 2 </TD> <TD WIDTH=32% VALIGN=TOP> 0..65535 </TD> <TD WIDTH=28% VALIGN=BOTTOM SDVAL="6" SDNUM="1033;"> 6 </TD> </TR> <TR> <TD WIDTH=18% VALIGN=BOTTOM SDVAL="32" SDNUM="1033;"> 32 </TD> <TD WIDTH=22% VALIGN=BOTTOM SDVAL="4" SDNUM="1033;"> 4 </TD> <TD WIDTH=32% VALIGN=TOP> 0..4294967295 </TD> <TD WIDTH=28% VALIGN=BOTTOM SDVAL="12" SDNUM="1033;"> 12 </TD> </TR> </TBODY> </TABLE> </CENTER> The number of colormap entries is defined by the colors keyword. The colormap data occurs immediately following the header (or image directory if the montage keyword is in the header). Immediately following the colormap data is the PseudoClass image data. PseudoClass image data is an array of index values into the color map. The number of bytes comprising the index value depends on the number of colors in the image. The following table shows the number of bytes in each colormap index as determined by the colors keyword: <CENTER> <TABLE WIDTH=72% BORDER=1 CELLPADDING=4 CELLSPACING=3> <COL WIDTH=77*> <COL WIDTH=80*> <COL WIDTH=99*> <THEAD> <TR VALIGN=TOP> <TH WIDTH=30% BGCOLOR="#52799e"> Colors </TH> <TH WIDTH=31% BGCOLOR="#52799e"> Bytes Per Index </TH> <TH WIDTH=39% BGCOLOR="#52799e"> Index Range </TH> </TR> </THEAD> <TBODY> <TR> <TD WIDTH=30% VALIGN=TOP> <=256 </TD> <TD WIDTH=31% VALIGN=BOTTOM SDVAL="1" SDNUM="1033;"> 1 </TD> <TD WIDTH=39% VALIGN=TOP> 0..255 </TD> </TR> <TR> <TD WIDTH=30% VALIGN=TOP> <=65535 </TD> <TD WIDTH=31% VALIGN=BOTTOM SDVAL="2" SDNUM="1033;"> 2 </TD> <TD WIDTH=39% VALIGN=TOP> 0..65535 </TD> </TR> <TR> <TD WIDTH=30% VALIGN=TOP> <=4294967295 </TD> <TD WIDTH=31% VALIGN=BOTTOM SDVAL="4" SDNUM="1033;"> 4 </TD> <TD WIDTH=39% VALIGN=TOP> 0..4294967295 </TD> </TR> </TBODY> </TABLE> </CENTER> If matte is true, each colormap index is immediately followed by an equally-sized alpha value. The alpha value represents the degree of pixel opacity (zero is totally transparent). The image data in a MIFF file may be uncompressed, runlength encoded, <A HREF="ftp://ftp.uu.net/graphics/png/src/">Zip</A> compressed, or <A HREF="http://www.muraroa.demon.co.uk/">BZip</A> compressed. The compression keyword in the header defines how the image data is compressed. Uncompressed pixels are stored one scanline at a time in row order. Runlength encoded compression counts runs of identical adjacent pixels and stores the pixels followed by a length byte (the number of identical pixels minus 1). Zip and BZip compression compresses each row of an image and precedes the compressed row with the length of compressed pixel bytes as a word in most significant byte first order. <A NAME="auth"></A>MIFF files may contain more than one image. Simply concatenate each individual image (composed of a header and image data) into one file. <TABLE WIDTH=100% BORDER=0 CELLPADDING=2 CELLSPACING=2> <TR> <TD BGCOLOR="#52799e"> <IMG SRC="../images/right_triangle.png" NAME="Graphic3" ALT=">" ALIGN=BOTTOM WIDTH=15 HEIGHT=14 BORDER=0>Authors </TD> </TR> </TABLE> John Cristy, <A HREF="mailto:magick@imagemagick.org">magick@imagemagick.org</A>GraphicsMagick Studio. <A NAME="copy"></A> <TABLE WIDTH=100% BORDER=0 CELLPADDING=2 CELLSPACING=2> <TR> <TD BGCOLOR="#52799e"> <IMG SRC="../images/right_triangle.png" NAME="Graphic4" ALT=">" ALIGN=BOTTOM WIDTH=15 HEIGHT=14 BORDER=0>Copyright </TD> </TR> </TABLE> Copyright (C) 2002 GraphicsMagick Group Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files ("GraphicsMagick"), to deal in GraphicsMagick without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of GraphicsMagick, and to permit persons to whom the GraphicsMagick is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of GraphicsMagick.
